2 Overview This Application Note efines Finisar implementation of the XFP -wire serial interface, which is use for serial ID, igital iagnostics, an certain control functions. The -wire serial interface is manatory for all XFP moules an it is efine in the XFP MSA Specification Rev 4.5. It is moele largely after the igital iagnostics monitoring interface propose for the SFP an GBIC optical transceivers an efine in the SFF raft ocument SFF-847 Rev 10.1, which in turn is an extension of the original serial ID systems efine for the GBIC an SFP transceivers. One major ifference, however, is that the memory structure is change to use a single -wire interface ar. IMPORTANT: The igital iagnostics functionality an memory maps escribe in this ocument apply to Beta-an Prouction-level units only. Please contact Finisar for information on Alpha-level units. As with GBIC an SFP transceivers, the XFP serial interface uses the -wire serial CMOS EEPROM protocol efine for the ATMEL AT4C01A/0/04 family of components. When the serial protocol is activate, the host generates the serial clock signal (SCL pin). The positive ege clocks ata into those segments of the memory map that are not write-protecte within the XFP transceiver. The negative ege clocks ata from the XFP transceiver. The serial ata signal (SDA pin) is bi-irectional for serial ata transfer. The host uses SDA in conjunction with SCL to mark the start an en of serial protocol activation. The memories are organize as a series of 8-bit ata wors that can be are iniviually or sequentially. The -wire serial interface provies sequential or ranom acc to 8 bit parameters, are from 00 to the maximum ar of the memory. The structure of the memory map is shown in Figure 1. The normal 56-byte IC ar space is ivie into lower an upper blocks of 18 Bytes. The lower block of 18 bytes is always irectly available an is use for the iagnostics an control functions escribe in this ocument that must be acce repeately. One exception to this is that the stanar moule ientifier byte efine in the GBIC an SFP transceivers is locate in Byte 0 of the memory map (in the iagnostics space) to allow software evelope for multiple moule types to have a common branching ecision point. This byte is repeate in the serial ID section so that it also appears in the expecte relationship to other serial ID bits. Multiple blocks of memories are available in the upper 18 Bytes of the ar space. These are iniviually are through a table select Byte which the user enters into a location in the lower ar space. Thus, there is a total available ar space of 18 * 56 = 3 Kbytes in this upper memory space. Rev C 009 Finisar Corporation AN-035 Page of 90

3 The upper ar space tables are use for l frequently to acc functions such as serial ID, user writable EEPROM, reserve EEPROM, iagnostics an control spaces. The upper ar space, is for future stanars efinition, as well as ample space for venor specification functions. These are allocate as follows: Table : Reserve for future iagnostic an control functions Table 01h: Serial ID EEPROM Table 0h: User-writable EEPROM Table 03h: - 7Fh Finisar-specific internal functions (not accible to the user) Table 80h FFh Reserve The etails of each memory space are escribe in the XFP MSA ocument. All -Wire registers are rea with bit 7 in the MSB first Figure 1: XFP -Wire Serial Interface Memory Map The memory structure also provies for an optional passwor entry location in the lower memory space that may be use to protect user-writable memory (Table 0h). A passwor is not require to rea any serial ID or iagnostics information in the lower memory ar space or in Tables 0h. A passwor is not require to write any Rev C 009 Finisar Corporation AN-035 Page 3 of 90

4 controls efine in the igital iagnostic functions escribe in the MSA ocument either. A passwor (entere into bytes 13 16) is require to allow write acc to the User EEPROM Table (0h). The efault passwor is h per the XFP MSA, an it can be change by the host manufacturer by writing the new passwor into bytes when the correct ol passwor has been written into bytes The host passwor must be in the range of to 7FFFFFFFh. The -wire serial interface ar of the XFP moule is X (A0h). In orer to allow acc to multiple XFP moules on the same -wire serial bus, the XFP pin-out inclues a MOD_DESEL or moule eselect pin. This pin (which is pulle high or eselecte in the moule) must be hel low by the host to select the moule of interest an allow communication over the -wire serial interface. The moule oes not respon to or accept -wire serial bus instructions unl it is selecte.

Power-on conition inclues a har-reset or hot plug of the XFP moule. The host nees to wait this amount of time, before running any ata traffic or checking for link status. In aition to this, if any IC transactions are carrie out uring this time, then the EEPROM contents rea, o not isplay the actual status of the moule, an instea are only the instantaneous reaings.

Other XFP variants will follow the same EEPROM template, however there may be slightly ifferent settings for some parameters in the XFP MSA Serial ID section. This application note, covers existing XFP moules that have succfully complete full GR-468 qualification.
